Hey guys, I just recently upgraded from a GK600 Backline and a crappy 410 to a 1001RBii & Neo410 (4ohmcab) combo. Lately I have noticed the tone has diminished so much that the lows, frankly, sound terrible. I play in Drop C mostly and no matter how much I tweek the EQ (I've tried boosted and flat) it still sounds awful. Another problem is when I turn the head on, it makes a loud 'POP' even when the tuning mute is engaged. Could this have something to do with it or is this normal? I certainly did not notice this with the GK Backline. Any help would be appreciated guys! Cheers in advance.
